Rule 13 is based on Fed.R.Civ.P. 13. This rule prescribes procedure to be followed in the use of counterclaims and crossclaims.

Rule 13 was amended, effective March 1, 2011, in response to the December 1, 2007, revision of the Federal Rules of Civil Procedure. The language and organization of the rule were changed to make the rule more easily understood and to make style and terminology consistent throughout the rules.

Subdivision (f), which set out standards for amending pleadings to add a counterclaim, was deleted, effective March 1, 2011, to track the 2009 federal amendment. The subdivision was redundant of Rule 15, which sets out standards for amending pleadings in general.

Subdivision (c)(2) was derived from Section 28-0907, NDRC 1943.

In 1971, subdivision (a)(2) was added and subdivision (h) was amended to include a reference to Rules 19 and 20.

Rule 13 was amended, effective March 1, 1990. The amendments are technical in nature and no substantive change is intended.
